URGENT: Which equation correctly uses the value of b to solve for a?


Triangle ABC is a right triangle and cos(22.6°) = [tex]\frac{b}{13}[/tex]. Solve for b and round to the nearest whole number.


OPTIONS:


1 ) tan(22.6°) = [tex]\frac{a}{13}[/tex]

2 ) tan(22.6°) = [tex]\frac{13}{a}[/tex]

3 ) tan(22.6°) = [tex]\frac{a}{12}[/tex]

4 ) tan(22.6°) = [tex]\frac{12}{a}[/tex]
